What was disputed, and how it came out

Each issue the panel decided, with the reasoning it gave. An outcome is what this panel did on this record — not a rule, and not a prediction.

Permanent disability ratingDefendant prevailed

WCJ correctly combined impairments rather than adding them; applicant failed to show non-overlapping ADLs

From the decision · page 3Further, the WCJ correctly combined and did not add the applicant’s impairments. “Impairments to two or more body parts are usually expected to have an overlapping effect upon the activities of daily living, so that generally, under the AMA Guides and the PDRS, the two impairments are combined to eliminate this overlap.” ( Vigil v.

ApportionmentApplicant prevailed

QME apportionment opinion failed to explain how and why pre-existing conditions caused permanent disability; not substantial evidence

The rules the panel named

Authorities as the decision cited them, with how this panel applied each one.

Escobedo v. Marshalls (2005) 70 Cal.Comp.Cases 604

Apportionment opinion must disclose familiarity with apportionment concepts, describe exact nature of apportionable disability, and set forth basis for opinion under correct legal principles

QME apportionment opinion rejected as not substantial evidence

From the decision · page 3(1970) 3 Cal.3d 372, 378– 379 [35 Cal.Comp.Cases 525].) “Moreover, in the context of apportionment determinations, the medical opinion must disclose familiarity with the concepts of apportionment, describe in detail the exact nature of the apportionable disability, and set forth the basis for the opinion, so that the Board can determine whether

Vigil v. County of Kern (2024) 89 Cal.Comp.Cases 686

Impairments to two or more body parts are combined to eliminate overlap in ADLs unless applicant shows non-overlapping or amplified impact on ADLs

Impairments combined rather than added

From the decision · page 3Further, the WCJ correctly combined and did not add the applicant’s impairments. “Impairments to two or more body parts are usually expected to have an overlapping effect upon the activities of daily living, so that generally, under the AMA Guides and the PDRS, the two impairments are combined to eliminate this overlap.” ( Vigil v.

What proof carried it

The evidence the panel weighed, by kind.

Evidence weighed

QME Dr. Robertson's apportionment opinion lacked explanation of how pre-existing degenerative disc disease caused permanent disability

From the decision · page 10Here the doctor failed to explain how and why the previous industrial and non-industrial conditions, e.g. degenerative disc disease, caused or contributed to applicant’s overall disability as a result of this instant industrial injury.

Evidence weighed

Applicant failed to provide evidence of non-overlapping ADLs to support adding rather than combining impairments

From the decision · page 4of Daily Living] impacted by each impairment to be added, and 2) Either: a) The ADLs do not overlap, or b) The ADLs overlap in a way that increases or amplifies the impact on the overlapping ADLs.” ( Id. at p.
